* BadassDecay: In ''Ancient History'', Ghost Tucker isn't as powerful as Tucker was when he had ghost powers. Justified as Danny believes that when he separated the ghost from Tucker and broke Desiree's spell, it DePowered Ghost Tucker.* BrokenBase: Despite the series' popularity, many fans are divided on the concept of Sam having ghost powers.* CharacterRerailment: ''A Family Thing'' undoes Vlad's MotiveDecay from the third season when he tries to brainwash Danny into his son.** Much to the joy of many fans, Tucker has returned to his pre-{{Flanderized}} state and is gaining true CharacterDevelopment.* DevelopmentHell: More than once, the author has had a frustrating time getting a story out.* GrowingTheBeard: Following ''A Family Thing'', the series seems to be coming into its own. Even WordOfGod has said that it was the story where the series would start really forming.* NightmareFuel: ** ''What She Wants'' revealed that all of the teens in Sidney's ghost Casper High will be there ''forever''. Sidney only gets out thanks to Desiree hearing him while on a wish-granting spree, allowing him to graduate. Now think of other students who are probably miserable like Sidney was and can't graduate...*** WordOfGod likes to wonder if they are real ghost students or rather just extensions of Poindexter, much like the band Ember had in her first appearance.** Vlad's MindControlDevice: Some little tiny ring shaped device can be stuck behind your ear, where no one will see it. It will completely override your thoughts and turn you into a puppet. Then a ghost like Vlad can turn intangible, sneak up behind you, and put it there.** Nocturnes's plan for Danny and Sam in ''Hearts and Minds''. Trapping them in a dream where they had no memory of each other was bad enough, but he actually attempted to steal all their dream energy and leave them trapped in a DeepSleep.** Danny's alternate ghost mode. Not only does it cause Danny to slowly become feral, but after using it for too long, the ecto energy will build up to the point where his body will burn out.* OfficialFanSubmittedContent: The author is willing to accept ideas from the readers. Many of the ideas he's used were suggested by the creator of this page. Fortunately, the author knows to avert TooManyCooksSpoilTheSoup.* PromotedFanboy: Invoked with many readers saying that the author should write for the actual show if it's ever revived. Yeah, he's that good.* RescuedFromTheScrappyHeap: Even the fans of Danielle should be happy that she's getting a lot of CharacterDevelopment in this series.* {{Squick}}: In-Universe example. Tucker and Valerie were visibly creeped out seeing Danny and Sam making out while Sam was dressed as Danny. Of course, many viewers have this same reaction upon seeing the [[http://tuxedaaron.deviantart.com/art/There-s-ALL-Kinds-of-Creepy-334979090 pic]] the author drew depicting the scene.* TechnologyMarchesOn: It's clear that Fenton Tech will become more advanced in the future now that Jack and Maddie are alive in it, as shown when Future Danny and Sam's Fenton Thermos can be compacted into a disk form.
